T all whom it may concern. Be it known that 1, JOHN F. Wins, a cit zenof the United States, residing at Chlcago, in the county of Cook, Stateof Illinois, have invented certain new and useful Imrovemcnts inCan-Closing Machines, of

which the following is a description, refermechanical means for feedinga can end from a stack underneath a seaming head, whereby the same isplaced for attachment to the can body.

A further object of the invention is to provide means for rendering saidfeedingin means ineffective, except when a can body is underneath theseaming head.

These and other objects will in part he obvious, and will in part behereinafter more fully describes. In the drawings which show by way ofillustration one embodiment of the invention,Figure1 is a; side view ofa closing machine .having my improvements applied thereto; Fig. 2 is aplan view of the sup porting plate for the stack of can ends, and thedevices for operating the pusher to feed in the can ends; Fig. 3 is asimilar plan View with the devices for operating the pusher broken away,and the controlling means for rendering the feeding-in deviceineffective, shown in topv plan; Fig. 4 is adetail View, showing thestack holder and the finger for rendering the pusher inefiective; fig. 5is a sectional view on',-the line 5 -5 of Fig. 4:; Fig. 6'is an enlargedview in side elevation, showing the controlling device for the feed-"ingin mechanism, with the parts in position to render the feedefiective; Fig. 7 is a similar view with the parts in position to renderthe feed ineiicctiveg and Fig. 8 1s a detail showing a modifiedconstruction of on a can end or cover, so as to form a double seam. Theseaming head 2 is mounted on a shaft 3, which is rotated by a bevel gearconnection i from a cross shaft 5, which in turn is operated from themain shaft of the machine. This seaming head. is moved up and down by alever 6.

The can bodies which. are to'be closed are mounted on a support 7, andare fed along the same by a drum feed 8, which consists of a drum havinga thread wound thereon, which thread extends above the support andengages the lower ends of the' can bodies. The filled can bodies arecarried by means I of this feed underneath the seaming head, and theseaming head is lowered, so as to bring the seaming rolls into properposition to act upon the cover or end to secure the same to the canbody.

Extending underneath the seaming head is a supporting and center'in'plate 9, which is mounted to move up and down in a bracket 10 secured tothe frame 1 of the machine. The supporting and centering plate isattached toarod ll,which is in turn con nected to a lug on the lever 6As the seammg head moves up and down, this support ing and centeringplate will move 11 and down with the seaming head. Said p ate ispositioned a suiiicient distance below the seeming head so as to allowthe seaming head to rotate and the seamin rolls to be brought intocontact with the ange on the can end to roll the same into a doubleseam. Centrally oi the supporting plate is an.

opening 12, which extends over the can body and serves to center thesame underneath the seaming head. Mounted on the supporting plate 9 is aholder 13 for a stack of can. ends. Said holder consists of a base plate14, and a series of rods 15, which hold the can ends stacked one abovethe other.

A pusher l6 slides through a suitable recess underneath the base 14, andis adapted to engage the lower can end in the stack and carry the samealong a guiding raceway to a supporting ledge 17,=surrounding theopening 12 and forming a seat for centering the can end underneath theseeming head. The cover rests on this supporting ledge, and as the plate9 is moved downward, the cover will be carried on to the can body, andwill be seated therein/by. the usual seating pad, after which it isengaged the chuck, so

taken from the stack 1 said finger istat the a, plunger .fore, that whenas to hold the can body stationary while the seaming head rotates aboutthe same to secure the can end on to the can body.

The pusher 16 is provided adjacent its 5 outer end'with a post 18. Tothe upper end of this post is pivoted a link 19, which is in turnpivoted to a rock lever 20 attached to the frame 1 of the machine. Theother end of the rock lever 20 is connected to a.link.21, which in turnis pivoted 'to a stud 22 that is "radially-adjustablein a disk 23mounted on a cross-shaft of the machine.

The link 19ispre'ferably made in sections, which'are connected togetherby a sleeve 24, so that the length of the link 19 may be varied tovarythe workingpositionfof the feeding-in pusher. rying the disk 23head, the rock lever 20 will be oscillated, and said lever through thelink 19 Will reciprocatethe pusher so that a can end will be and placedon the supporting ledge at each reciprocation of the pusher. The stud 22may be ad usted radially on the disk 23, so as to vary the stroke ofthe. pusher. By this adjustment and the' adjustment of the link 19, I amable to control the stroke of the pusher, so that can ends of difier'entsizesmay be fed to the seaming headand properly posltionedcentrallyund'erneath the same. WVith-jthe above mechanical means forfeedingiilrthe can ends, it will be noted that a can endis fed Ito thesaminghead for each reciprocation of the seaming head. In order-{toprevent" the feeding in of -can ends when there is no'canbody-underneath thehead to receive the can end, l 'jh ave-provided acontrolling means for rendering the feeding-in devices effective orineffective, in accordance with whether can bodies are being fed to theseaming head. f Said controlling means, as herein shown, consists of afinger 25, which is mounted so as to, slide backand forth in asupporting-bracket 26 attached to the supporting plate 9; This fingerprojects throughthe base 14 into the stack. holder, so that the lowercan end in a stack will rest-at one side on said finger. The finger isso dis 0 posed relative to t e pusher 16, that when inner endofitsstroke, flasshown in Figs. i and 5, the can endswill raised so thatthe stack, and, there-, .igiegwhen. thetfinger is at the inner end ofaidfeeding-in means will be er 2 5 is moved back and forth by 27, whichis formed at its lower ,en'd with ih'uvertical portion 28,'and aninclined portibn 29. These parts 28 and 29 areadapted tovmove in anopening 30 in the: finger 25. It will readily be seen, therethis plungeris moved from the position shown in Fig. 5 to -its extremel As the crossshaft carrotates with the seaming l upper position, that the finger 25will be withdrawn from the stack holder sufficiently to allow thestacked can ends to descend and ii the lowermost end to be placed in thepath W of movement of the pusher. When the plunger is moved again to theposition shown in Fig. 5, the finger will be moved into the stackholder. i

The inner end of the finger 25 is tapered 7.5- at 31, so as to aid inlifting the stack or passing underneath the lowermost end in, the stack.A plate 32 is secured to the u per face of the pusher 16. .on the sidethereoFadjacent the finger 25, to aid in holding the stacked ends sothat the finger 25 may be with"certainty moved underneath the sametosupport the ends at one side thereof. The plunger 27, is provided withtwo spaced collars 33, which are fixed thereto. A 35 lever 34 is pivotedat one end to a bracket 35, and is formed with a ball collar 36intermediate its ends, which rests between the fixed collars 33 on theplunger 27. 'he lever 3-Fat its outer end is pivpted at 3'1 99 toa'controlling pad 38. A weight 39 is se cured to the lever 34. It isobvious, how ever, that in place of said weight any-de sired means maybe used for depressin the outier end of the lever 34. The contro ling pafilled can on thefeedingjdevice, whichis to be carried underneath 38 ispositioned so as to extend over the b 0-0 device, as the forth, the canpoint within the path of-the controlling plllld 38, the next downwardmovement 0 seaming head, which: carries with it the supporting plate 9,the stack holder and the 9 feeding-in devices, as well as thecontrolling finger, will cause the' controlling pad to 'engage the 'toplof: the t can body, which will limit the downward movement of theouterend of the lever 34'. '-The further downward I 'movement'of theplatefl9 will cause the" lever "34 to swing'about its fulcrum on thebracket the pusher will move underneath the can ends without engaging-55- the lower, can-end in after anotheralong the support 7, the 0011-supporting ledge mes es trolling means will operate at each movement ofthe seaming head to allow a can head to be engaged and moved on to the17. If, however, the oper-- ator fails to position the can body on thefeeding-in mechanism, so that during one operation of the seaming headno can body is present to be closed, then the controlling pad 38 willmove down with the plate 9, as there is no can body in the path ofmovement of the controlling pad, and the fin er will not be releasedfrom the stack hold er 'l" he finger is returned to its normal positionsupporting the ends in the stack holder by the weight 39.

It is sometimes desirable floating contents of a filled can prior to theplacing of the can end on the same. In order to accomplish thisdepressing of the contents, I may form the controlling pad 38 with. adownwardly projecting center pen tion'lO, which substantially ts theinner side of the filled can, and will depress the floating contentsinto the can body. Said controlling pad is provided with. a ledge 41,which engages the edge of the can body and limits the downward movementof the pad end support for so as to operate the controlling finger.

It is obvious that minor changes in the details of construction maybemade, without departing from the spirit of my invention, as set forth inthe appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
